------------------------------------------
Summary: Storm cluster metrics do not show up because of AMS
aggregation issue.
Key: AMBARI-17845
URL: https://issues.apache.org/jira/browse/AMBARI-17845
Project: Ambari
Issue Type: Bug
Components: ambari-metrics
Affects Versions: 2.2.2
Reporter: Aravindan Vijayan
Assignee: Aravindan Vijayan
Priority: Critical
Fix For: 2.4.0
PROBLEM
Storm cluster metrics (aggregated across hosts) don't show up in Ambari and
Grafana
BUG
Storm metrics collect and send data in 1 minute intervals. Since their data is
present in the right end of the spectrum for the 2 minute aggregator
(start_time ~ server_time), a bug in the second aggregator is causing these
values to slip between 2 aggregator cycles.
FIX
Within the 2 minute interval, look for the data in the time shifted interval (
ams-site:timeline.metrics.service.cluster.aggregator.timeshift.adjustment). In
case no data is present, look for the data outside the right boundary of the
interval. Use that to interpolate the data in the 30second slices.
